@rzepsen I think I have the same problem like SusiWG. I´m using WooCommerce Blocks and my new field is not shown: https://equili.at
(You can buy all courses, only I will get the orders). I already tried to delete the code on Pages –> WooCommerce Checkout Page and replace with [WooCommerce_Checkout] as you recommended, but this doesn´t work too? Instead the code is shown as text “[WooCommerce_Checkout]” and the checkout-page is away.
What can I do?
Can you help me please?
